Application filed August 2,1921. SerialI T0.=4= 9,331.

Be it-kiiown that'iI, ANGELO A. Sriino, a citizen ofthe United States, residing at 800 East 101st street, New York, in the county'of NewfYork and State of New York, have invented certain new and useful Improvements in Embroidery Frames, of which the following is a specificatiom T his 'IDVEIIUOII relates to frames, especially frames: of a collapsible nature commonly used foifithe niaking or working of embroidery the drying-or dyeingof fabrics; or the liken v i I I Among the objects ofthe invention is to provide-a framei embodying I a plurality of framemembers or bars-adapted to be connected-to one another "at rightan-gles or at any other desired angle and'at any suitable relative length between the adjacent "angles orcorners- Another obiectfofthe invention is to provide a means for attaching twoadjacent bars to each other with the utmost convenience and facility, and yet providing means wherebyz'all 0f the "bars may b'emaintained connected F to one another permanentlvif (lei sired though they may be collapsed in form. A-still further objecttis to improve the meansfoia'attaching the work to the frame. W ithwthe foregoing and other objects in view, but without restricting the invention unnecessarily as :to' materials, design, or the like, reference is had to the accompanying drawings; intwhich similardparts are referred to by like refe-rence characters and in \VhlCl1 Figure -1 is a plan view showing, .a .preferred embodimentiof theinvcntion in sembled position.

Thesebars maybe of anvsuitable length ordiinension and they mav'be'made of any suitable material, commonly a nice. quality of wood suitable for taking a smooth anddurablefinish; Each bar is shown as substantially fiatand withrounded parallel sideedges 12 and 13. The upper portion of eachbar adjacent to the edge-13 is rabbeted. at 14' for the permanent attachment of a strip 15- of flexible. material such as fabric to which-the Work may be pinned, tacked oriotlierwise secured temporarily while -.in place on the frame. The-strip 15 lS SlIOWII folded or doubled uponv itself at 16 where it is laid into the rabbet 14 and beneath the Y to parallel main uppersurface of the bar. so thatthe' baror any other object that may be positioned upon or placedto move over said upper surface will, not be a slot 17, of any suit l obstructed by thestripc 15.interferingwith such movement or causis formed along; each end rOr'lOCfltiOll with respect-to the I nature similarIto the slots 17 biit=.mei-g-'.

ing at one end into an circular or cylindrical enlargement 19 of form; The. cross sectionsofthe slots; 17 and .18 may be exactly the same, OFlf desired one may be narrowcrwthan the. other. FromFig. l it; will be noticed, that any bar 10 or 11 may be adjusted longitudinally of itself ineit-her 5 direction because of the slots formed therein. and it maybe adjusted zlaterally of itself and with respect to all of the other bars because of theslots in theamembers overlapped b v thebar being adjusted As illustrated in Fig. l the frame as a whole is ad- 'just-ed to form an open central rectangular .orsquare space 20 that isrelatively small in dimensions, and that; with" adjustment'ofthebarsoutwardfr'o n said center the space;

Ina-3 be-increased because of the length of a i A Anyrsuitable means may be provided to connect the adjacent bars to each other, the means I prefer for this purpose being a bolt 21 adapted to pass upward through the slots in said bars. Any suitable kind of bolt may be used for this purpose, including The head 22-is a head 22 and a'nut 23. preferably unusually broad and flat, coming squarely against the bottom surface of upward from the shoulder 2a is shownas considerably reduced in diameter for' the accommodation of the spring 26 coiled therearound of an outside diameter not exceeding the width of the slot 18 along which it may glide when the, nut is loose. The normal tendency of the spring is to expand or elongate so as'to hold'the washer 27 spaced freely above the upper surfaceof the bar 11, if the washer is used as shown in Fig. 5,- although the nut 23 may be pro. vided with abroad washer-like base 27 as shown in Fig. 1. is wide enough to more than span the slot 18 and yet such washer and nut will pass upward freely through the enlargement 19 at the end of such slot18 during the assembling or disassembling of the frame. The washer 27 may bear squarely against the upper surface of the bar 11, but preferably I employ a pair of metal reinforcements 28 alongthe' edges of each slot to-or marring of the upper surface of the bars 11 because of bearing contact of the nuts or washers. The washer 27 need not be used if the nuts are wide enough to span the slots 18. Since there is no rotation of the bolts in the slots 17, and the heads 22 and the bolts are broad and flat, no Washers are needed between the heads and the I against: the

bars 10;

Ordinarily the bolts are never removed fromthe slots 17. If the frame is disassembled assemblage thereof will be effected as follows: Bars 10 with th connected thereto are laid across any suitable base such as a table or chair backs at an 1 nulends of the bolts upward. The bars 11 are thenclaid across the bars 10, the fabrio strip edges of the bars being toward thecenter. of the space within the frame. With the bolts carried loosely in the slots 17 the operator'then simply moves the bolts along the circular openings 19 while the bolts are held with their heads 22 from beneathbars 10. The broken lines in Fi 3 show how the springs atthis time hold the Washers 27. up against the nuts The washer or base 27" nuts.

or the base 27 ofthe nut 18 asto prevent damage bolts suitable distance apart and with the in such position that-the bolts may be moved relatively along the slots 18 from the openings 19 without requiring the operator to reach down into the openings to bring the wwashers up therethrough size desired for the frame. When this position is reached the thumb of'the hand grasping the bar 10 will be free naturally to bear upon the bar 11 holding the bars in an approximate position while with the other while with the other hand the nut will be tightened to clamp I the bars as desired. therefore be removed from the bar 10' at any time. For ordinary purposes the'frame may be foldedor collapsed simply by loosen- The bolts need not ing all of the nuts so as to allow thebarsof each pair to come close against each other as shown in Fig. 2 and in thls posltionthe bars may be held firmly simply by tighten ing one or more of the nuts. 'Another purpose of the springs 26 is to insure a smooth action of the clamping means for adjustment of the bolts and for tightening of'the They are however not stiff enough to make any material difference in the tightening of the nuts.

I claim: l

1. In anadjustable frame, thecombination of a plurality of bars arranged inpairs, all of said bars having bolt openings therethrough, the openings being slots having enlargements at 1 their ends clamping membersfitted permanently in one pair of bars andhaving nuts adapted to pass freelythrough'said enlargements of the openings in of one pair ofwbars the other pair of bars and movable thence along theslots thereof, a I

washer surrounding each clamping-member, and a spring also surrounding the same member and acting on the washer to hold it against the nut, substantially as set forth.

2. let-device as set forth in claim 1 1n which the bars having the slots terminating 1 in enlargements are profvidedwith metal reiinforcing strips along the edges'of the slots to take the, wear of the nuts. R

3. A device as set forth in claim 1' in which the bolts are provided with'squ-are shoulders fitting slidably in slots in the bars to whiclrthe bolts are permanently attached, said bolts having reduced shanks around which the springs arefitted bea'ring at one end against the shoulders-and at their other ends toward the nuts, the springs being movable freely along the slots of the bars. having the enlargements.
